I've been using a GTX 690 to game at 1440p for most of the year. In general it's done very well, but I've been running into some framerate issues, namely Fallout: New Vegas (modded to hell and using an ENB) and Tomb Raider. The compromises to run them well aren't major, but I was just offered two vanilla R9 290s for $370. I'm pretty tempted, but I know I'll have to buy into an aftermarket cooler, which is going to raise the price $100 at least.
So the question is, do y'all think it's worth selling the 690 (should be able to get $450-500 for it) and swapping out for R9 290 crossfire? Or should I buy into newer gen hardware?
